The [[Nokia N950|N950]] is the second [[Maemo]] / [[Harmattan]] device which can be used as a phone. It is a development platform for the [[Nokia N9]].

It is only available to developers, and not as a consumer product.
It shares much hardware with the [[Nokia N9|N9]], with the notable differences that the display is TFT, not OLED, and there is a hardware keyboard.

Due to the use of different display technologies, on the N9, developers should avoid one pixel width fonts(?) and graphical objects with lines one pixel wide. Also avoid the extensive use of bright colors, especially white, when developing for OLED displays as this increases the power consumption (typical for OLED displays). See [http://en.wikipedia.org/wiki/PenTile_Matrix_Family this page on common OLED pixel arrangements for more info]

==Display==
N950 has 4" (480 x 864, limited by software to 480x854) TFT display created by AU Optronics.

==Features==

===Accelerometer: LIS3LV02DL===

Sysfs attributes under /sys/devices/platform/lis3lv02d/:

* position - 3D position that the accelerometer reports. Format: "(x,y,z)"
* rate - read reports the sampling rate of the accelerometer device in HZ.
* write changes sampling rate of the accelerometer device.
Only values which are supported by HW are accepted.

* selftest - performs selftest for the chip as specified by chip manufacturer.

By default output values are scaled between -32768 .. 32767

===="freefall" device====

It supports blocking operations, poll/select and fasync operation modes.

You must read 1 bytes from the device.  The result is number of free-fall
interrupts since the last successful read (or 255 if number of interrupts would not fit).

=Software=

The OS is maemo-6, codenamed Meego-[[Harmattan]]. The core OS still is maemo based and unrelated to http://www.meego.com/ though APIs and the UX are in some cases similar to meego_proper.

Nokia seems to refer to this device as N9-devkit: https://www.developer.nokia.com/Devices/MeeGo/#article2   http://www.engadget.com/photos/nokia-n950-press-shots/#4243171
